'BURNlSHING-MACHINE.

fiiPECIFICATION forming part of Letters Patent N 0. 356,842, dated February 1, 1887. Application file-d September 18, 1886. Serial No. 213,938. (No model.)

To ctZZ whom it may concern:

Be it known that I, GEORGE E. KELLEY, residing at Rockford, in. the county of innebago and State of Illinois, and a citizen of the United States, have invented certain new and useful linprovementsin Burnishing-lliachines, of which the following is a full description, reference being bad to the accompanying drawings, in which- Figure 1 is alongitudinal section of the drum or cylinder and its shafts; Fig. 2, adet-ailshowing the construction and application of the burnishers; Fig. 3, a detail of the angular portion of the burnishing-rod with its sides partly broken away at the ends; Fig. 4, a perspective view, and Fig. 5 detail of a dripfaucet. Fig. 4; is on a reduced scale.

The object of this invention is to provide a machine in which the articles to be burnished can be easily attached and detached, to make the machine continuous in its operation,.and to generally improve its construction and operation.

The nature ofiny improvements Willbe found embodied in the claims.

In the drawings, A represents the bed-plate; A, the baseplate; B, aliquid-reservoir; ab 1), the cylinder or drum; 0, elastic or rubber covering; d, a tableknife in position; 6, sockets or holes for the reception of the articles to be burnished; f, the upper or inner ring of the cylinder; g, the outer ring, having a flange, h; ij, shafts; 7r, i'riction-clutch; ZZ WOLIH'WhGBlS; Z Z", worms; m, shaft-cap; a, hand-wheel; o, screw-cap; p, angular section of the burnishing-shaft; p, its supporting bracket or box, q, section of burnishingshal't carrying the burnishers; 7', adjustable connection for the pitman s,- t, crankwheel having an adjustinggroove, 1.; a c, cone-pulleys; '0, arms or sockets for attaching the burnishers to their bar; to, springs; a, movable shafts or spindles carrying the burnishing-tools; y, power shaft and pulley; 3 belt, a b" c, spring'clips for holding the upper or outer end of the articles to be burnished; cl, support for reservoir; e, pipe from reservoir, having branches f; g, dripfaucets; h, cut-off valve or stop.

The bed-plate A can be made in the form shown or in any other suitable form, and it is to be connected to or with the base-plate A,

as shown, or to any suitable supporting-table or framework, and it will be readily understood t-hat the machine maybe operated when in either a vertical or horizontal position or at any intermediate angle.

The drum or cylinder at is preferably cast in the form shown, with its supportinghub Z) projecting inwardly. The outer end is provided with a band,f, which partly holds the elastic rubber or bed in position, and to which the clips or clamps cb c are attached. These clips are made as shown in Fig. 1, the part a being pivoted and given a proper pressure to hold the end of the article by the spring I), which bears against the arm or projection c, which is rigidly attached to the ring f. The inner end of the cylinder is provided with a metal ring, 9, which has aflange, h, projecting slightly above the lower end of the rubber or other elastic bed.

The knives d, or other articles to be burnished, have their points inserted under the flange h and their upper ends clamped and held by the clamp a. The spring 1) allows the arm a to be opened for the purpose of inserting and taking out the articles.

The bed 0 is made of a continuous rubber band entirely surrounding the cylinder at, and provided with suitable molds or recesses, 83 e, to receive'projecting portions of the articles to be burnished. These. molds or recesses willvary according to the shape or contour of the articles to be burnished, the form shown being adapted to table or case knives. Dift'er- 8 5 cut rubber beds may be applied to the same cylinders; but ordinarily it will be preferable to have complete cylinders adapted to the different articles to be burnished where there is any considerable difference in shape or length.

The flange 71, with the ring 9, is usually made adjustable, so as to lap more or less over the cylinder, and removable so that the covering 0 may be changed without removing the ring f, and for this purpose the projecting 9 5 flange at the lower or inner end of the cylinder is omitted and the inner portion of the ring g made wider and provided with any suitable attaching and adjusting devices; but this will not be necessary when only one kind ion of article is to be burnished. Thecylinders a are primarily supported upon the shafts t,

which are hollow, and through which the shafts pass.

The worm-wheels Z are attached to or made a part of the shafts i, and the outer end of each 5 shaft is provided with a beveled recess to receive the friction-clutch k, which has a correv spon ding bevel. The friction-clutch is attached to the shaftj by means of a screw, so that it can be thrown into or out of operation by turning the hand-wheel a, which is attached thereto at or near the opposite end, and held in place by the screw-cap 0, which may also be used tothrow the clutch into or out of action. The shaft 7; is also provided witha cap, 122., against which the hand-wheel it bears, and which prevents the cylinder from getting out of position, and, being provided with a v screw;it is made to clamp against the hub I) ofithezcylinder, and thereby compel the rotamention ofthe cylinder with the shaft. The shaft i :isisupported in the brackets or bearing-boxes i, and the shaft is reduced in diameter, as us rshownhin Fig. 1, at its bearing-points, and i (provided with shoulders, so that the shaft 2' QSUQOBSNIIQt have any endwise movement. The

aiiinnenends of these shafts are provided Wit/hi iavormi -awheels Z, which are driven by the ,2 :ivormsn-Za These worms are supported in '2 isuitablebearings, or by the bed-plate through oawhichthey pass, and between this and the 1 J. base plate they are provided with worm-t :wheels-Z, operated by secondary worms Z .a'iwhichiare driven by the cone or conical pulzlley aQawhich is connected with its opposite 135 cene-zpulley'za by a cord or other suitable belt,

aar'elalwaysi in .theisame relation to the cylinw ders when in operative position, and thefeed is from the side, they cannotget out of place when limit devices are omitted.

The burnishingwheels or tools in the outer ends of the arms a are of the usual construction, and they may be all alike, or they may given them by moving the wrist-pin in the slot it toward or from the center of the cranbwheel t and theposition of all? may bechanged by screwing the section 0' in or out, so as to lengthen or shortenithe distance betweenthe inner end of the pitman and the sectionp, which carries the section qr This change of position may be made at any time by simply'unshipping the pitman from the wrist-pin or the wheel t and giving the screw-section r l a suitable numberof turns to obtain the desired position when the pitman is replaced. The groove t is a dovetailed groove, and the wristpin is attached to a suitable block sliding in said groove, which may be provided with a set-screw or other device to lock or hold it: in the desired position.

The liquid-reservoir 1B is supportediby the standard or post d, and it is elevated sufficiently to give a slight pressure in the tubes. f, and it is provided with atube or pipe, 6, having a stop or cut-off valve or plug, h. The pipe 0 is forked, and its branches f are located over the burnishing-to0l,%so that the drip from the faucets y will be inthe proper relation to the tools and the article being burnished. The tubes f maybe re-enforced by collars where the faucets g passthrongh them, and the upper side of the passage is screwthreaded, as shown in Fig. 5,,full size. The

IIO,

stems of the: faucets are tapered to a point; 7

which extends below the tube and forms a guide for properly directing thedrip, which drip may beincrcased, diminished, or cut off by turning the stem, as by turning it backward the screw portion of the stem lifts it so as to increase the drip+space, and turning it forward diminishes or closes the dripspace, so ithatthe amount of drip can be easilyregulated. The pipes f, instead of being forked from the pipe e,may lead direct from the reservoiryand additional pipes leading to other machines may be connectedwiththe reservoir B. The liquid placed in the reservoir is such as is ordinarily used in burnishing.

It will be understood that by the use of the hand-wheel neither or both cylinders can be stopped without stopping the entiremachine, and that when the friction-clutch is thrown off the cylinders may be revolved: by hand in either direction, so as to enablethe operator to discharge the entire number of articles bum nished and to refill the cylinder, if itis desired to so operate the machine; but the motion of the machine is such that the burnished articles may be taken out and fresh articles supplied without stopping the machine, so that its operation may be continnous,if it is desired to operate it in this manager.

The preferable size for acylinder is one which will hold fortyeight articles to be burnished; but it is evident that the cylinders may be adapted to a greater or less number, as the elastic bed-plate and the springs 10 will cause the .burnishing-tools to come in proper contact where the articles do not conform in line or shape to the surfaces of the cylinder.

By this construction I obtain a simple and efficient burnishing-machine, which can be operated either continuously or in any other manner, as may be desired, which is simple in its construction and efficient in its action, and the movements and operations are such that a number of machines can be operated by a single attendant, and thereby greatly reduce the labor and cost heretofore required in burnishing small articles.
